2 W E U T a w d E ATTORNEY res DRAW STRING- BAG AND METHOD OF MAKING 'rns SAME Edward E. West, Richmond, Va. Application July 29; 1931. Serial No. 553,742 8 Claims. ((31. 150'11) The present invention relates to draw string bags and more particularly to the construction at the mouths thereof and to the method (of making the bag..

' 5 The principal objects of the invention are to provide, draw string bags which are neat in appearance .andisturdy, in that they are not.:likely to rip at seams formed at marginal portions thereof {and to provide a method of making draw stringbags by which. production is facilitated, the operatives being able to ,do betterf work more rapidly than according to theusual methods which have been practiced for quitesometime. It is a usual practice in the making of a draw string bag to provide at the top margin of a blank, a hem extendingfromsideto side;

thread a stringthru the passage formed by the hem so that the end portions of. the .string protrude from thehem passage.v at thesides of the blank; foldthe blank along a medial line between the sides of the blank so that thelopen ings ofthe hem passage are adjacent one an-.

other; sew a seam from the folded edge Ciel 111G.

blankalong the bottom and then along. the meeting sides, but when approaching the hem,

run or curve the line of stitching. off to the: side edge and not clearto the top, otherwise the thread may run thruor soqcloselyto one or. :both of; theIruns of stringin the hem passage,

as to prevent free drawing action; and finally turn the bag inside or right side'out so that the raw-marginal portions along the seam are inside thebag' j r This results in a finished bagwhich is not neat-in appearance. The mouth portion flares outwardly at one side of the bagcwhere the line of stitches was run off in a curved path to. the edge of the blank before reaching the top of the hem, toavoid sewing the draw string tight.

After the bag has been drawn closed, the ten ency of .a person when opening the bag is to use the index fingers projectinginto the mouth of the bag to draw it open. If much force is exerted the result is that the bag will start to rip alongthe seam since the stitches terminate in a frail portion of the bag According to the present invention the hand of the hem passage remote from the sides of the blank, preferably by. slitting the hem inwardly from each side of the blank a distance to permit.

bag or disarrange the warpand weft of a fabric grasping ends of the draw string are led out 7 opened in the manner abovedescribed-ripping 0 I is resisted for the stitchesfare a sufficient distance remote from'the raw edges of the bag body portion. to not disrupt the fibres of the bag.

' Before explaining in detail the present immovement and mode ofoperation thereof, I de-' sire to have it understood that-the invention is not limited to the details of construction and arrangement oi parts which are illustrated "in the accompanying drawings since the invention is capable of other embodiments, and that the phraseology which I employ is for the purpose of description and not of limitation.

In the drawings, .A designates a strip of material, such as cloth, paper, etc., from which the bag blank B may be cut; C the drawstring material from which the draw string D maybe cut; E a line of stitches of a hem F; .G a line of stitches of seam H along the bottom of the bag; and J a line of stitches of 'seam K along the side of the bag...

I The strip of bag materialis preferably of a width equal to the length of the desired bag; plus suflicient material to provide the hem F and the seam H. The hem F is provided by doubling the material upon itself one or more times and running a line of stitches "E longitudinally of the strip providing a hem passage 7 to accommodate the draw string material C. Thishem is provided with slits 8 at spaced intervals longitudinally of the hem thru which loops 9 of draw string material may be drawn; as shown in Fig. l. Insofar as the present-method 1S concerned, it makes no difierencewhether the slits 8 are provided-before,-during or after the hem is formed, however, in the aforesaid copending application is shown apparatus whereby the slits are provided after 'the hemis com-. pletely formed. The draw string material C Q may be laid or strung in the passage 7 of the I the slit portionsj'thereof and where the; bight which extend from the slits 8 hembefore, during or after its formation and likewise the loops 9 may be drawn from the slits; before,-during orafter completion of the hem.

The dot and dash lines 10 indicate-wherethe' bag material is'cut transversely of the hem at portions 11 of'the loops 9 of draw string material 4 are cut to provide the blank'B shown in Fig. 2.

The'cutting of the bag m'aterial and draw string," may be simultaneous, or'one may be cut in ad This cutting of the draw,

Vance of the other. string material provides finger grasping ends 12 hem, as shown-in Fig. 2 I

' Taking the blank as shownin Fig. 2, if it is desired that the folded over portion 15 of the hem be ultimately on the inside of the finished bag, the bag body 13 is 'folded'upon'itself as shown at 14 in Fig. 3, with the folded over portion 15 of the hem outermost the line of fold 14' being "parallel to and-midway between-the end margins 16 of the bag-body;

Prior to'providing the lines of stitches G and H, the end margins 16 are brought together so that the slitted hem portions are in juxtaposed relation as shown in Fig. 4: It is immaterialwhether the line of stitches Gfor J is first formed, or whether they are run "off to the edges at the bottom of the bag or continued without cutting the thread, one of the principal characteristics of the invention being the line of stitches 18 extending entirely across the hem F, so that the finger grasping ends 12 are between theseam K and the fold 14, as clearly shown in Fig. 4."In this connection it may be observed laterally of the observe the approach of the hem, as when sewing from the bottom toward the mouth 19 of the bag.

' While, the bag may be used in the condition shown in Fig. 4, it is preferably turned inside out, or right side out, as shown in Fig. 5, thus concealing the raw edges of the seams H and K. It will be noted from Fig. 5 that the bag is no wider" at its mouth. portion than at any other portion, thus providing a bag neat in appearance and reinforced against ripping since the line of stitches 18 extends entirely across the hem F,

the finger grasping ends 12 of the draw string protruding from the slits 8 at points intermediate the seam K and the body fold 14.

It is to be understood that, by describing in detail herein any particular form, structure or arrangement, it is not intended to limit the invention beyond the terms of the several claims or the requirements of the prior art.

-.Having thus explained the nature of my said invention and described a way of constructing and using the same, although without attempting to set forth all of the forms in which it may be-made. or all of the modes of its use, I claim:

1. A bag comprising a body portion having. a seam along a side thereof and a hem at itstop, saidhem provided in its folded edge with slits extending to the edge of the seam, and a draw string in the passage of the hem, and having finger'grasping ends extending thru the inner end portions of the slits to the exterior of the hem;

'2. A bagblank having a hem along-onemargin thereof, said hem provided in its folded edge Witha slit extending inwardly from each end thereof, and a draw string in the passage ofthe hem having finger grasping ends extending out of the slits laterally of the hem.

3. Those steps in the method of providing a bag which consist in providing a blank with a 'hemalong one edge, forming openings in the folded po'rtionof the hemremote from the sides of the .blank, then inserting a draw string in the passage of the hem with finger grasping ends extending out of the foldededge of the hem remote from the sides of the blank, doubling the blank upon itself to provide a bag body and so that the hem. ends are adjacent one another,

and'stitchingthe bag body and hem to provide a seam running entirely across the hem with the draw string between the seam-and the body fold.

4. Those steps in the method of providing a bag which consist in providing a hem and a draw string in the passage of the hem along the marginof the bag body material, slitting the hem at spaced points and drawing portions of the draw string from the slits to provide finger grasping portions'extending laterally from the hem, doubling the body material upon itself so the slitted hem portions are in juxtaposed relation, and stitching the bag body across the hem with the finger grasping portionsof the draw string between the line of stitches and the body fold.

5. Those steps in the method of providing a bag which consist in providing a hem, forming openings in the folded portion of the hem remote'from the sides of the blank, then inserting a draw string in the passage of the hem along the margin of bag body material, drawing portions of the draw string from the'passage of the hem in the folded edge thereof to provide finger grasping portions extending laterally at spaced points from the hem, doubling the body material upon itself so that the .portions of the hem from which the finger grasping portions extend are 'in juxtaposed relation, and'stitching the bag body across the hem with the finger grasping portions of the draw string between the line of stitches and the body fold.

6. Those steps in the method of providing bag blanks which consist in providing a hem at the longitudinal margin of strip bag material and v stringing adraw string in the passage of the hem, slitting the hem at spaced apart intervals, drawing loops of draw string from the slits, cutting the bag material transversely of the hem at theslit portions thereof and the drawstring a the bight portions of the loops.

7. Those steps in the method of providing bag blanks which consist in providing a slitted hem at the longitudinal margin of strip bag material,

the slits being spacedapart longitudinally of the hem and string a draw string in the passage of the hem, drawing loops of draw string material
